There are a lot of places in California named after saints. And since the Spanish missionaries were here well before any English-speaking Americans (or the Russians, who came down from Alaska and left their mark on place-names like Russian River), these towns start with San or Santa, depending on the saint’s gender. As in San Jose, Santa Barbara, San Rafael, Santa Clara, and, of course San Francisco. This one I found on a shop sign near Washington Square.
Never heard of that Saint.

I’m no expert in Japanese but In fact I believe it means “3000” in Japanese.
– San is Japanese for 3
– Sen is thousand. (but takes on a Z sound following a voiced consonant line “n”)
3000 Nails?
I always thought it meant “Without Nails.”
i think theres no saint with that name hehe it sounds more like japanese
zen is a schools of buddhism, 1000 is “sen”.
I cannot believe how everybody is taking my little joke so seriously. It was all about San, as in San Francisco. I do know what Zen stands for, except on nail studios.
nah, the joke is well received. just showing off my uber-weak japanese :]
